Jemini, Soulless Mage

Protection From Instants and Sorceries, Lifelink

You may cast noncreature spells by paying life equal to their mana cost. Spells your opponents cast cost additional 5 life to cast. Spells cast this way have Flashback until end of turn.

Whenever a creature dies, exile it and you gain 3 life and each opponent loses 1 life. If it was a creature you control, do not exile it and draw cards equal to its toughness and then discard cards equal to its power instead.
